Retroreflectometer QualiRLQD™
Retroreflectometer QualiRLQD™ is a portable field measurement device designed to assess the brightness of road markings as they appear to drivers under vehicle headlight illumination at night. It measures the retroreflection properties of road markings, specifically the luminous retroreflection coefficient (RL value), expressed in mcd·m⁻²·lx⁻¹. This instrument is widely utilized by road marking manufacturers, construction teams, and quality control organizations to evaluate the retroreflective performance of road markings.
